The Lowdown
Alright, Rusty here. Let's have a look at what's coming up for Lakey Pipe.
Overall, we're looking at a solid run of swell, but the wind is a bit of a mixed bag. The biggest issue for the next 10 days or so is that cross-off breeze. It's not terrible, keeps things pretty clean, but it leaves the waves a little wrapped. For the first week, the wave energy is quite strong, with readings in the moderate to high range, like 4029 on Sunday the 13th.
The water is at 80°, which is pretty much just normal for this time of year. Nothing weird going on there.
The real standout window kicks off around Sunday the 27th of September. That’s when we see the energy jumping up big time, with readings like 3324 and 3974, and then hitting over 4000 on the 28th. The swell period on the 27th morning is a massive 22 seconds—that's proper groundswell, real long lines of energy that will be peeling beautifully down the reef. The afternoon of the 27th looks excellent with a 2 ft swell from SSW and light south-easterly winds.
But Monday the 28th of September is the pick of the whole period. The swell builds to a solid 8 ft from SSW, with that very long period of 18 seconds. The winds are light from the SE. The wave energy is massive (4185 in the morning, 3388 in the afternoon). This is going to be pumping, but let's be real—at 8 ft with that much power on a reef, this is for experienced surfers only. It’ll be one of those days you tell stories about, but you need to know what you're doing. Because it is a consistent spot that is often crowded, you’ll want to be out there early.
Rusty.

Information about the Lakey Pipe Surf forecast
The above surf forecast table for Lakey Pipe provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Lakey Pipe can be found by selecting the local surf guide option on the grey menu. Our Lakey Pipe surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Lakey Pipe) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Lakey Pipe may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
